Appearance
Adults appear during late May to the beginning of August being most active in the evenings. Females lay their eggs in a piece of decaying wood. Stag beetle larvae, which are blind and shaped like a letter "C", feed on rotting wood in a variety of places, tree stumps, old trees and shrubs, rotting fence posts, compost heaps and leaf mould. The larvae have a cream-coloured soft transparent body with six orange legs, and an orange head which is very distinct from the very sharp brown pincers. They have combs in their legs which they use for communication with other larvae. The larvae go through several developmental stages, taking 4 to 6 years to become pupae. The work of entomologist Charlie Morgan during the late 1970s discovered that the pupae of the stag beetle live in the soil for about 3 months, then emerge in summer to awkwardly fly off to mate. Adults only live for a few months feeding on nectar and tree sap. Their slow, lumbering flight, usually at dusk, makes a distinctive low-pitched buzzing sound. The males fly more readily than the females. The modern Italian word for a toy kite "cervo volante" may derive from the ancient amusement of flying the beetles on a length of thread.The natural reaction of the beetle to an approaching large object is to remain motionless making them a good photographic subject. Sexually dimorphic, the males have enlarged mandibles and are larger than the females. Although the male's mandibles seem threatening, they are too weak to be harmful. Nevertheless, females can inflict a painful bite. It is the resemblance of the male's mandibles to the horns of a stag, and their use in combat between males, much like with deer, that gives the species its scientific and common names.
